WINDING DEVICE.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed December 27, 1919. Serial No. 347,761.

To all whom it may concern:

Be it known that I, HARRY P. LEE, a citizen of he United States, residing at Stonington, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in \Vinding Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in winding apparatus and more particularly has reference to an adjustable device for winding threads of yarn, silk, cotton, or other material such as wire, string and the like and for unwinding the same as requirements may vary, and is illustrated in the accompanying drawing as an attachment for use upon a winding machine.

In said drawing, l2 indicate the bearings upon which the hub-like structure 3 is secured. at indicates a cylindrical portion of said hub-like structure upon which the memher 5 provided with a series of cuts 6 is mounted, and 7 indicates a pin adapted to engage any of said cuts accordingly as said member 5 is rotated.

8 indicates suitable wires or rods pivotally mounted as indicated at 9 upon the member 5 and offset at the ends as indicated at 10 to engage the sliding arms 11 adapted to be adusted radially within the tubes 12 secured in the cylindrical portion at of the hub-like member as shown. The offsets 10 are such that the wires or rods 8 tend to shift the member 5 in the direction of the observer looking at the drawing so that after the member 5 is rotatably adjusted so as to bring the pin 7 in alinement with the particular cut (3 which it is to engage, the same is locked securely therein and the slidable arms 11 are radially adjusted the desired extent according to the winding or unwinding operation to be performed.

13 indicates the yokes or carriers at the outer extremities of the arms 11 upon which the coil of thread, wire, or string is mounted preliminary to the unwinding of the same or upon which the same may be secured for winding.

From the foregoing it will be readily observed that the size of the coil to be used for the winding or unwinding operation may be readily adjusted to any predetermined extent and where the coil is to be unwound it will also be readily appreciated that it may with convenience be placed upon the several holders 13 after which by rotating the adjusting member 5 the rods 11 may be projected suliiciently to engage the coil with proper tension for retaining the same during the unwinding operation.

It is well known that various devices have heretofore been provided for adjusting means for winding and unwinding operation, such devices generally employing pinions and various other detailed mechanisms for providing for such adjustment. This invention is therefore addressed more particularly to the means employed for providing for the adjustment which said means are simple in operation, convenient to manipulate, and inexpensive to construct while providing a durable and efficient device for the purposes described Of course it will be understood that various modifications may be made in the con struction and arrangement of parts without departing from the spirit of my invention as claimed.

1 claim:

'1. In a device of the class described, a hub bearing and slidable arms thereupon and means in combination therewith for radially adjusting said arms, said means comprising a rotatable member upon said bearing and connection thcrebetwecn and said slidable arms, said rotatable member upon said bearing having slots circularly arranged and an engaging member upon said bearing adapted to engage one or said slots, and said connection between said slidable arms and said rotatable member being adapted to normally maintain engagement between one of said slots and said pin.

2. In a device of the class specified, the combination with a hub, of arms slidablc radially of said hub, an adjusting-member rotatable and slidable axially of the hub, links pivoted to said adjusting-member and connected to slide the arms, detent-means for holding the adjusting-member rotatively of the hub, and resilient means for sliding the adjusting-member to engage the detentmeans.

3. In a device of the class specified, the combination with a hub, of arms slidable radially of the hub, an adjusting-member rotatable on the hub and slidable axially thereof, wire links pivoted to the adjusting-memher and connected to slide the arms, said links being held under tension tending to slide the member on the hub, and detent means engaged by the sliding of the member under the tension of the links.

4. I11 a device of the class described, a hub bearing and slidable arms thereupon, and means in combination therewith for radially adjusting said arms, said means comprising a rotatable member upon said bearing and connection therebetween and said slidable arms, said rotatable member upon said bearing normally projected axially therefrom, 10

means upon said hub for engaging said memher when so projected and for releasing the same when moved in the direction of said hub.

In testimony whereof I hereunto afiix my 1 signature.

HARRY P. LEE.
